Cell phone video of an arrest that was shared on Twitter has prompted an investigation.

My dog started barking about 10 mins ago there was some banging in the parking lot. I look out and the white truck that you see surrounded by the cop cars was driving around the parking lot, smashing into other cars when they boxed him in and got him out. #YEGpic.twitter.com/NOtVMkI4SJ
